WooCommerce 结帐页面上使用多个复选框的条件电子邮件收件人？

Question

我将不胜感激以下任何帮助...

在我的 WooCommerce 结帐页面上，我需要允许我的客户选择他们的多个首选经销商，然后将新订单电子邮件发送给我自己和他们选择的经销商。

我这辈子都不知道如何使用多个复选框进行设置，这将允许他们选择多个复选框（即他们选择分销商 1 和 3，只有我们三个人会收到新订单电子邮件）。

我能够使用下拉菜单找出答案（感谢阅读了该社区中的各种帖子）。任何帮助将不胜感激！ :)

我能够拼凑的当前代码（只是有点为自己感到自豪，因为它确实有效）：

// // Add custom checkout field
add_action( 'woocommerce_after_order_notes', 'sj_custom_checkout_field' );
function sj_custom_checkout_field( $checkout ) {
    echo '<div id="sj_custom_checkout_field"><h2>' . __('Distributor') . '</h2>';

    woocommerce_form_field( 'my_field_name', array(
        'type'      => 'select',
        'class'     => array('wps-drop'),
        'required'  => true, // Missing
        'options'   => array(
            ''          => __( 'Select Your Preferred Distributor', 'wps' ),
            'Distributor 1'   => __( 'Distributor 1', 'wps' ),
            'Distributor 2'      => __( 'Distributor 2', 'wps' ),
            'Distributor 3'    => __( 'Distributor 3', 'wps' ),
            'Distributor 4'    => __( 'Distributor 4', 'wps' ),
            'Distributor 5'    => __( 'Distributor 5', 'wps' )

        )
    ), $checkout->get_value( 'my_field_name' ) );
    echo '</div>';
}

// Process the checkout
add_action('woocommerce_checkout_process', 'sj_custom_checkout_field_process');
function sj_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( empty( $_POST['my_field_name'] ) )
        wc_add_notice( __( 'Please select your preferred distributor.' ), 'error' );
}

// Save the custom checkout field in the order meta
add_action( 'woocommerce_checkout_update_order_meta', 'sj_custom_field_checkout_update_order_meta', 10, 1 );
function sj_custom_field_checkout_update_order_meta( $order_id ) {

    if ( ! empty( $_POST['my_field_name'] ) )
        update_post_meta( $order_id, 'my_field_name', $_POST['my_field_name'] );
}

add_filter( 'woocommerce_email_recipient_new_order',  'new_order_conditional_email_recipient', 10, 2 );
function new_order_conditional_email_recipient( $recipient, $order ) {
    if( is_admin() ) return $recipient;

    // Get the order ID (Woocommerce retro compatibility)
    $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;


    // Get the custom field value (with the right $order_id)
    $my_field_name = get_post_meta( $order_id, 'my_field_name', true );


    if ($my_field_name == "Distributor 1")
        $recipient .= ',1@email.com';
    elseif ($my_field_name == "Distributor 2")
        $recipient .= ',2@email.com';
    elseif ($my_field_name == "Distributor 3")
        $recipient .= ',3@email.com';
    elseif ($my_field_name == "Distributor 4")
        $recipient .= ',4@email.com';
     elseif ($my_field_name == "Distributor 5")
        $recipient .= ',5@email.com';

    return $recipient;
}

或者，select 和 radio 类型具有相同的参数，您可以将您的 select 更改为 radio。如果您确实需要样式看起来像复选框，请使用 css to make radio looks like a checkboxes。

woocommerce_form_field( 'my_field_name', array(
    'type'      => 'radio',
    'class'     => array('wps-drop'),
    'required'  => true, // Missing
    'options'   => array(
        ''          => __( 'Select Your Preferred Distributor', 'wps' ),
        'Distributor 1'   => __( 'Distributor 1', 'wps' ),
        'Distributor 2'      => __( 'Distributor 2', 'wps' ),
        'Distributor 3'    => __( 'Distributor 3', 'wps' ),
        'Distributor 4'    => __( 'Distributor 4', 'wps' ),
        'Distributor 5'    => __( 'Distributor 5', 'wps' )

    )
), $checkout->get_value( 'my_field_name' ) );
